I would contact your server administrator and ask them to delete that folder for you.

If that is not possible, I would try renaming it (e.g. to "junk") and moving it out of your public_html folder (i.e. to your home folder). The easiest way to do that is to open two Fetch connections, one to your home folder (/) and the other to /public_html/wp-content/plugins/wp-gbcf, and drag the junk folder from one window to the other.
